STATIONERY-CABINET.

Specification of Letters Patent.

Patented May 28,1912.

Application filed November 27, 1911. Serial No. 662,617.

To all whom it may concern:

Be itknown that I, THOMAS A. Mn'r'riinws, a citizen of the UnitedStates, residing at Nashville, in the county of Davidson and State ofTennessee, have invented certain new and useful Improvements inStationery- Cabinets, of which the following is a specification.

My invention relates to stationery cabinets such as shown in my Patent-748,967, Ja11u ary 5, 190%.

The object of the invention is to improve the paper-feeding mechanismshown in said patent. This object I accomplish by the mechanism shown inthe accompanying drawings, in which:

Figure 1 is a perspective of my improved cabinet. Fig. 2 is aperspective of the paper-feeding mechanism removed from its casing; thepaper lifter having just lifted or buckled a sheet of paper. Fig. 3 is asectional side elevation showing the paper feeder in the act of feedinga sheet through the delivery opening. Fig. 4 is a perspec' tive of thepaper lifter removed. Fig. 5 is a perspective of the bottom of thecabinet.

A designates the cabinet of any suitable material and construction andprovided in its front with an opening A about as high as the ile ofpaper to be contained within the cablnet. The bottom of the cabinet hasan inclined portion A on which the paper P rests; the high end of theincline being about in line with the lower edge of opening A and spacedfrom the cabinet front. The rear end of the cabinet has a door A for theintroduction of the paper. Secured to the base of the cabinet at thesides and lower end of the incline A are the adjustable gages or guidesA* for the pile of paper.

Within the front end of the cabinet at opposite sides thereof arevertical guides A connected at their upper ends by a cross bar A", andbetween these guides A slides an inner panel B, working between thecabinetfront and the front end of the incline A This sliding panel B hasa horizontal slot registering with the openin A, in the cabinet frontthrough which t e paper is fed, as will be presentl described.

The panel B is provided at its ends with uprights B having outwardlyprojectin notched uide lugs b at their upper an lower en s; saidnotchedlugs sliding on the vertical guides A. The n per ends of theuprights B are connected y a cross bar I),

and below the cross bar the uprights arc progidcd with inwardlyextending brackets 04 s The sliding panel B is provided at the loweredge of its slot B with an inwardly extending flange or lip B whichrests on the pile of paper, and the upper edge of the slot has a guideflange or lip B parallel with the flange B to guide the paper throughthe slot B. The lip or flange B is firmly held by an inclined brace 12.

C is the paper lifting arm secured firmly to an oblique shaft C, mountedin an angle bracket C secured to the inner face of the sliding panel Bjust above the left hand end of its slot B. The shaft C has at one end asprocket wheel 0 actuated by a crossed chain c, the upper portion ofwhich engages a sprocket wheel 0 carried by one end of a transverseshaft C mounted in the brackets b, b above described, and provided atits opposite end with a sprocket wheel 0 The sprocket wheel 0 is engagedand operated by a chain c", the inner portion of which engages asprocket wheel 0 carried by a transverse shaft 0 mounted at the upperend of a standard A extending up from the bottom of the cabinet. Thisshaft 0 is pro vided with a bevel gear 0, which meshes with a similargear cl on the inner end of the longitudinal shaft D, which is the 0crating or driving shaft of the paper-feeding mechanism. The inner endof the main shaft D is mounted in a bracket a on the upper end ofstandard A and the outer end of said shaft extends through a bearing inthe fixed front of the cabinet and is provided with an operating crankor handle D.

The lifting arm C has an anti-friction roller 0 journaled in a recess inits free end and projecting beyond one side of said arm, whileprojecting from the opposite side of the free end of said arm C is afriction device 0 When, therefore, the main shaft D is rotated a singlerevolution the arm C will be rotated toward the front of the cabinet,and when the roller 0 engages the paper the arm will act as a cam andslightly elevate the panel B, by which it is carried, and so raise theflan e or lip B from the paper, the top sheet 0 which, at its forwardedge, will then be engaged by the rearwardly moving friction device 0and moved rearwardl from under the lip B which will then escend upon thepile and the friction device will release the free edge of the buckledsheet which will then slide forward upon the upper side of the flange orlip B ready for forward feeding, as will be described.

The paper is fed by a forwardly turning curved arm or cam E secured to ashort transverse shaft a mounted in the forked end 6 of an inclined armA, the upper forward forked end of which is loosely hung on the shaft CThe shaft C is provided within the upper forked end of arm E with asprocket wheel 0 from which a chain 6 leads to a sprocket wheel 0'' onthe shaft 6.

The feeding arm or cam E has a friction surface 6 of rubber or othersuitable material. The inclined arm E is held from imparting its weightto the pile of paper by means of a supporting arm E extending from crossbar I) with its lower hooked end E extending under the upper fork of thearm E. The arm E is apertured for the passage of the shaft C It will beseen, therefore, that the rotation of the drive shaft will, throughshaft C, which is indirectly geared thereto as described, first causethe lifting arm C to release the front edge of a sheet of paper, andthat said edge will then spring forward upon the flange or lip B afterwhich the continued rotation of drive shaft will, through the feed armE, also geared thereto, feed the paper through the slot B and opening Ain the cabinet front from which it may be pulled by the fingers of theoperator.

As the lifting mechanism and the feeding mechanism are carried by thesliding panel A, the relative relation of the same to the slot A remainsthe same and the chain a is sufliciently slack to allow of the verticalmovement of the panel A and its attached gearing. The chain 0 is heldfrom displacement from sprocket wheel 0 by a guide arm F projectinginwardly from panel A.

An arm G in the form of a spring extends inwardly from the guide flangeor lip B across the pile of paper to a point adjacent to the feed arm E,and prevents the top sheet from buckling up between the lip B and thearm E in case its front edge should not be lifted from beneath theflange or lip B at any rotation of the lifting arm C.

The drive shaft D is provided with a ratchet disk (1 having a singlenotch (Z engaged by a spring pawl (13* depending from the stationary topbar A". This pawl and ratchet permit the rotation of the drive shaft Din one direction only and stop it at every complete cycle of theoperation. A coiled spring D on shaft D between disk (2 and the frontwall of the cabinet exerts sufficient friction to prevent lost motion ofthe drive shaft.

H is a vertical rack bar secured at its upper angle end to the cross barI) of uprights B and at its lower end to the bracket 6*, with itstoothed edge It facin the drive shaft 1). The shaft I) is provlded witha thin sheet metal pawl cl which snaps into a tooth every time the pawlcl enters the notch d and holds the panel B with its lip or flange Bslightly above the top sheet while the parts are at rest. This pawl dallows of the descent of the sliding panel as the pile of paperdiminishes.

The cabinet proper may be made as in my Patents 787,966 and 787,967, ifdesired.
